The effect of physics computer simulations on teachers’ misconceptions of DC circuits

Abstract

The behaviour of direct current (DC) circuits in the electricity section of undergraduate and school curricula is a source of a multitude of common misconceptions. Our study is a pilot project to determine the effect of physics computer simulations on teachers’ misconceptions of DC circuits in a local non-urban environment. The simulations are highly visual, as well as physically accurate. Three intensive workshops were presented to Further Education and Training (FET) physical science teachers in a region of the Tshwane North District. The goals of the workshops were to improve teachers’ understanding of electric circuits, to improve the skills associated with connecting lights bulbs, resistors and wires in various combinations and let teachers think and argue about the behaviour of the circuits. Data was collected from pre- and post tests, worksheets, informal interviews as well as evaluation forms. Some of the misconceptions could be resolved and will be discussed.
